Summary: The lignite chemical looping combustion and hematite as an oxygen carrier were studied in this paper. By analyzing the thermodynamic behavior and conducting experiments, it was found that increasing the oxygen carrier to lignite mass ratio could reduce the release of NH3 and HCN. The release of HCN increased with temperature, while NH3 release decreased. Increasing the gas flow rate resulted in higher NH3 and HCN emissions. Modifying the oxygen carrier with Ni and Cu improved oxidation performance and significantly reduced NH3 and HCN emissions.

Summary: Chemical looping co-gasification of alfalfa and polyethylene with Fe2O3 as oxygen carrier was studied in a fixed-bed reactor, revealing that at a gasification temperature of 950 degrees C, the optimum product distribution was achieved with specific ratios of steam/alfalfa, OC/alfalfa, and PE/alfalfa. The presence of PE in the feedstock led to higher production of synthetic gas, particularly the hydrogen yield, as the H-2/CO ratio increased to more than 2 to match the demand of Fischer-Tropsch synthesis.

Thermal behavior, product yields and characteristics were analyzed to study the influence of biomass species and blending ratios on co-pyrolysis synergistic effect. The results showed positive synergistic effects on char and liquid production, with weakened synergy in liquid production when waste tire was blended. Co-pyrolysis also had positive synergistic effects on CO and CO2 generation, but negative synergistic effects on H2 and CH4 content.

Summary: This study investigated the effects of sodium on coal combustion and NOx emissions in Zhundong coal. The results showed that water-soluble sodium had negative effects on coal conversion and NO generation during traditional combustion. However, when chemical looping was applied to Zhundong coal combustion, the NO emission was largely restrained and mainly came from pyrolysis. Additionally, the gasification agent facilitated NO generation and CO2 had a stronger effect on chemical looping.

Summary: This study presents and compares two different pathways of lignin conversion to bio-jet fuel from corn stalks. The one-step conversion pathway yields higher bio-jet fuel and cumulative exergy efficiency compared to the two-step conversion pathway. Biomass conversion to bio-jet fuel with self-supplied hydrogen aids in converting low-quality biomass into high-quality bio-jet fuel and reducing fossil fuel consumption. Sensitivity analysis shows that the hydrolysis efficiency of lignin has the greatest impact on cumulative exergy efficiency, while the furfural yield from hemicellulose has the lowest impact.

Summary: Anaerobic digestion is a promising method for reducing sewage sludge and recovering energy. A comparative life cycle assessment was conducted to evaluate different anaerobic digestion processes. The results show that anaerobic digestion combined with cogeneration and digestate incineration is advantageous to high energy recovery, but incineration is disadvantageous to economic performance. The study also revealed that the environmental damage is largest in the process of thermophilic anaerobic digestion with digestate incineration, while the smallest load is in mesophilic anaerobic digestion with digestate landfilling. Overall, thermophilic anaerobic digestion combined with thermal hydrolysis pre-treatment exhibits the best resource performance, and digestate incineration and CAD-2 show better comprehensive performance. The deep drying incineration process has better comprehensive performance than sewage sludge anaerobic digestion processes.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
